tion of the invention, such as will enable others skilled in the art to which it apper tain's tomake and use the same.

This invention relates to screens, and is more particularly adapted for use 1n connection With windows, and has for one of its objects the provision of a screen which may be made in any suitable size for fitting the windows for which the same is intended.

A further object of this invention resides in the provision of a screen which may be attached to any window without the necessity of making any alterations inthe window frame or sash construction.

A still further object of this invention resides in the provision of a screen which may be permanently attachedgto the window frame, and which will not interfere with the operation of the sashes orobstruct the manipulation of the blinds whether the same is outside or inside. And a still further object of this invention resides in the provision of a screen having a guard arranged thereon for cooperating with one of the window sashes to provide a close fitting screen and to thereby prevent the ingress of insects between the window pane and the screen. And still another object of this invention resides in the provision of an efiicient insect guard capable of being placed against the window pane, or readily re moved therefrom when necessary, which will not interfere with the raising or lowering of the sash, and also furnishing means for engaging the under portion of the upper rail of the sash whereby the screen and the sash may be raised in unison.

In addition to the above objects, this invention also resides in the provision of a screen which may be positioned either at the lower portion of the window or the upper portion, or at any desired intermediate point and retained in any of the desired adjusted positions by frictional contact with its mountings, and further the screen may be readily attached to or detached from the window construction if'it'is so desired to remove the screen altogether.

I Specification of Letters Patent.

Patented May 18, 1915.

Theseand other objects will more fully I appear and the nature of the invention will be more clearly understood by the construction, combinatlon and arrangement of the parts thereof as described in the following'specificatlon, defined in the appended claims andv the accompanying drawings,"

illustrated in 1n wh1ch v o Flgure. 1 1s a vertical transverse sectional view of a window construction showing the application of the screen within the window frame. Fig. 2 is a horizontal sectional view on line 22 of Fig. 1, showing the upper rail of the screen and the manner of hingedly mounting the insect guard thereupon, the lnsect guard being shown in contact with the window sash.-

The frame of the screen constituting my invention, as well as the insect guard arranged thereon, may be formed'ofmetal, wood, fiber, or any suitable material where in the same may be constructed embodying the elementary features of this invention.

Referrmg'to the-drawings, 1 denotes the sill, 2 the lintel, and 3 the sides of the window frame, l'the guide strips arranged in the sides 3'between which are adapted to travel the sashes, and 5 is the retaining strip for the inner sash. Within the window frame is mounted the usual upper sash G and .thelower sash :7 having the usual upper meeting rails 8 designatedfor the bars 11, is provided with the elongatedgroove 14: of sufiicient dimension for receiving the U-shaped portion of the guide strip 9 and to cause the side rails 11 of the'screen frame to frictionally engage the guard strips 9 for retaining the screen'frame in any desired adjusted position. At the upper inner edge of the upper bars 12 of the screen frame adjacent the lower sash 7 are the hinges 15 and secured to the hinges 15 at its lower inner edge is the insect guard bar 16. The ends of the guard bar are formed of the configuration of the beaded or grooved portion of the sash construction as at 17 to provide a close fitting connection between the ends of the bar 16 and the side bars of the sash 7. The bar 16 is further provided with the handle 18 or other suitable hand gripping means for manipulating the bar 16 when desired.

For conveniently raising and lowering the inner sash 7 I provide upon the top rail thereof the handle 19 or other suitable hand gripping means.

20 represents the usual window casing provided with'the compartment 21 for re ceiving the weights and cords of theusual window construction.

In the application of the screen constitutingthis invention, to a window,'the metallic guide strips 9 are attached tothe retaining strips 5 of the window frame, the strips 9 snuglyv fitting within the grooves 14 of the sides 11 of the screen frame. The insect guard bar 16, which in this instance would be normally resting upon the upper surface of the top bar 12 of the screen frame would be then revolved upon the hinges 15 'out wardly until the bar 16 contacts with the pane of the sash 7 thus closing the space between the upper bar 12 'of'the screen frame and the pane of the'sash 7 thus preventing passage of insects over the screen and into the room. The screen is capable of being positioned in any desired position and may be used to screen the lower sash or the upper T sash, and should it be desired to raise both the screen and the lower sash it is only necessary to force the screen upwardly, having previously placed the bar against the pane of the sash whereby the bar 16 will engage the under surface of the bar 8 of the sash whereupon the screen 10 and the sash-7 may be raised upwardly in unison, thus allowing when it is desired to raise both the screen and the sash simultaneously, it is only necessary to grasp the handle 19 of the sash 7, slightly elevate the sash until the bar 16 can be passed beneath the bar 8 and in this instance the screen and the sash may also be raised together.

While I have here shown and described the preferred embodiment of my invention I hereby reserve the right to make such alterations and variations therein from time to time as I may deem expedient and which will not depart from the spirit of the invention nor conflict with the scope of the appended claims.

Having thus fully described my invention what I claim as new and desire to secure by Letters'Patent of the United States is The combination with a window, the frame, sash and glass thereof and a window screen, slidably mounted upon the inner edges of said frame, of an insect guard bar hingedly mounted upon the upper cross bar of said screen, removably contacting the inner surface of the glass of the lower sash comprising a single piece and formed to it the configuration of the beaded portion of the sash construction, whereby insects are prevented from entering between the said screen and the said glass.

In testimony whereof I have signed my name .to this specification in the presence of two subscribing witnesses.

GEORGE H. LAMBERT.
